The original was specified in a much more compressed form (for instance
there was a table with one line per SoC to describe the port node, the
YAML equivalent has to be longer).

With your recommendation of using pattern instead of enum for the dclkin
clock names, we're down to 848 lines, it's already a bit better :-)
I could indeed split the file, but I'll then run into naming issues. If
you look at the compatible strings for each of the if...then...else,
they don't have easy patterns that could be used to name files. I could
name the files based on one arbitrarily chosen compat string among the
multiple values that are supported, but I think that would become
confusing. I could also have one file per SoC, but we'll then end up
with lots of files, several of them being totally identical except for
the compatible string. Would you mind keeping it as-is, or do you think
it really needs to be split ?

When you say I can drop "this", which part do you mean exactly ? I
indeed wanted to specify that no other property than remote-endpoint can
be present. What's your recommendation ?

I assume you meant
- pattern: "^dclkin\\.[01]$"
Will fix.

It's a nice reminder that we should add support for it. And I don't
meant in the driver, even if that part is also required, but in the DT
bindings. I don't want to blindly state
port@2:
description: TCON
without working on TCON support on the driver side to validate that the
DT binding is fine and that I haven't overlooked something. Do you mind
keeping the comment for now ?
